At present, when the surface of a shell such as a mobile phone, an MP3, an audio, or a surface of a shell that is combined into a locomotive appearance is given a color overcoat, the main splashing process, the wet process, and the gel (SGl_gel) process are three. class. The process is to use the yellow light process to form a majority of money on the surface of the shell, and the difference in the thickness of the film caused by the interference of light, and then the change of the LL Zhuang Wang Ba shape, the advantage of a method is based on the semiconductor process Years of development 铖:: at!? The control of environmental protection and regulation is better. The use of:: The production of seven c疋 is difficult for the surface of the set surface to be a curved surface or a non-horizontal continuous surface, and the larger the area, the greater the difficulty of production. The human,, and type processes mainly use electrochemical, electric shovel, and electric chemical reaction, such as electroforming 'χ, and the surface coating on the surface of the shell is given to the color wheat · drf · # t 1 A to apply the complex 卞Color enamel, although this method can be used, the surface of the surface, or the non-horizontal etc. when the production is made ♦ ' However, to electrify the wind cow itself as a conductor, or to make it a conductor, this 5 200911560 The material is not suitable for non-conductor materials (such as plastic) or double-alloy materials such as aluminum alloy, which means that the process is limited and not widely applicable. The gel process is to uniformly coat the gel solution (coating) on the surface of the shell by gravity or centrifugal force. In the production, the control of the local color system and the film thickness is not easy, and the production precision is not high, which is a major problem. It is the goal of the industry to develop the most concise and effective production method and to give the surface of the shell a bright surface. SUMMARY OF THE INVENTION [4] The present invention (4), that is, in providing a molding method, is to form a pattern film with a variable longitudinal depth on the surface of the shit member, and can easily and effectively achieve the effect of imparting a bright surface to the surface of the shell member. . In the present invention, a molding method for forming a wood film having a variable longitudinal depth on a surface of a shell member includes a coating step, a stabilizing step, an embossing step, and a curing step. . The coating step is spraying or coating a layer of the film to be embossed on the surface of the shell member, and the stabilizing step is performed to stably spray the shell member to be coated with the layer to be printed, so that the layer to be imprinted is stably and the shell member The surface is attached. The embossing step controls a rolling head along the set path to the film to be embossed: the surface travels 'recording travel (four), the towel advances along the thickness direction of the material: braking' and the layer to be embossed is formed to have a longitudinal depth The pattern film corresponding to the pattern of the S-roller is changed. The curing step causes the patterned film formed by the imprinting step to cure. = Efficacy in the Qingtou can be along the path of travel =::: move ', so that the (four) printed film layer is formed with a longitudinal depth of the way; the pattern of the head of the film, in the simplest and most effective way to give the surface a continuous curved surface or Non-horizontal continuous surface shell color coating [Embodiment j The following and other technical content, features and effects, in the detailed description of a preferred embodiment of the clearing diagram, the invention can be A preferred embodiment of the longitudinal "degree changeable method" is formed on the surface of the shell member, comprising - a planting step μ, and = 2, an embossing step 13, and a curing step 达到 from the member 21 to the colorful The effect of the coating. - The layer is made of sorghum, coated on the surface of the shell member 21, or coated with the printing film layer 22; the thickness of the panel is suitable for the surface shape of the shell member. (4) It is sprayed. Therefore, the shell surface is continuous, non-horizontal continuous surface, or continuous curved to obtain the thickness of the film layer 22 to be embossed. The piece 21 is connected = % 疋 step 12 is statically sprayed with the to be embossed The shell of the film layer 22; this step stabilizes the surface of the TM 21 _ 5 to 60 minutes. The constituent materials and formation of the layer 22 Degree, the static fit is referred to FIG. 2, and then the embossing step 13 is performed to provide a driving device 200911560, and the rolling head is used to "snap the smashing movement" relative to the casing member 21 along the set path. When the embossing film layer 2 is pressed in the process of ST, the film can be rolled. I: The film layer 22 forms a pattern film 23 having a longitudinal depth variable and corresponding to the pattern of the dust head η. . In this example, the surface of the rolling head 31 having a finely scribed pattern (not shown in the figure) is driven by the device 32, and rolls and travels along the set path on the surface of the egg U to be embossed (shell member 21). It is fixed, and the rolling head 31 is linked by the two wheels 321 . By the shape of the cam 321 , the cam 321 : when moving, will brake the rolling head 31 to reciprocate along the thickness direction of the film layer 22 to be pressed. When the rolling head rolls and displaces along the surface of the film layer 22 to be imprinted, the rolling head 3 is also interlocked! The pressure (not greater than iw) pressed against the layer 22 to be imprinted is changed, and thus the film layer 22 to be formed is formed. The pattern film 23 of the pattern of the longitudinal depth is reduced; that is, by the cam 321 = ^, the film 23 is formed corresponding to the load pressure of not more than the core, and the micro scale of the pattern 臈 23 is not larger than 200nm. In addition, the cam 321 of the continuous rolling head 31 can be replaced by other means such as a link mechanism and a line motor, so that the pressure of the rolling head pressing against the pressure of the P film layer 22 can be changed, and the film layer to be embossed is formed. 22 forms the purpose of forming the pattern film 23 deep in the longitudinal direction. In other applications, it is also possible to design the driving device to drive the shell member (moving the shell member) to move the rolling head relative to the shell member, and when the driving device drives the (four) piece, the rolling head is rolled relative to the surface of the film to be imprinted. When the movement and the value are shifted, the cam brake rolling head changes the pressure which is applied to the film layer to be pressed, and is also applicable to the pattern film to be embossed film 8 200911560 >, having a longitudinal depth variable and corresponding to the pattern of the rolling head Referring to FIG. 1, finally, a curing step 14 is performed to cure and shape the pattern 臈23 which has passed through the embossing step, so that a pattern film 31 having a pattern having a variable longitudinal depth can be formed on the surface of the shell member 21, Thereby, the pattern film 31 causes interference with light to achieve the effect of imparting a bright coating to the shell member 21; in this example, it is at 8 ° C to 9 (TC hot baking for 1 minute or less to make the pattern The film 23 is solidified and shaped, such as by ultraviolet light, or selectively cross-linking the material of the film to be printed 22, and ultraviolet rays and heat are used for baking to shape the pattern 23, which is a method that can be used. One, , , Figure 3, according to the experiment, in the rolling head 3 1 When the pattern is not designed, when the load applied force of the rolling head 31 is in a smooth parabolic relationship with the traveling path, the depth profile of the film layer 22 to be pressed has a corresponding arc curve; therefore, when the rolling head 31 is designed When the pattern is patterned, not only the film to be imprinted can be laminated and formed to have a change in depth, but also a corresponding pattern can be formed, thereby causing interference of light by the pattern film 23 having both the depth variation and the pattern. To achieve the effect of giving the shell a colorful coating. Referring to Figure 4, in addition, the pressing pressure of the rolling head 31 and the traveling path can also be a continuous wave trough (such as a sinusoidal state), or concave and convex The grievances of the city (ie, as in the square wave pattern) 'then embossed the pattern film 23' of the groove pattern as shown in FIG. 5 or FIG. 6 and according to the experiment, at this time, regardless of whether the surface of the shell member is a continuous plane or a non- The horizontal continuous surface or the continuous curved surface, the micro-scale of the patterned film 23 thus formed can still be maintained below 2 〇〇 nm, and the precision is not more than 10%', thereby achieving the effect of brightly covering the shell member 21. 9 200911560 + The above description shows that this book The main purpose is to provide a coating step η for coating the film layer 22 on the shell member 2, a stabilizing step 12 for stably adhering the layer of the film to be imprinted to the shell member 21, and a control (4) head 31. The path travels on the surface of the (four) printing film layer 22, and is braked in the row material=thickness of the dust-removing film layer 22, and the film layer μ is formed to have a longitudinal depth variable and corresponds to the rolling head 31. The embossing step U of the patterned film Μ and the forming method of the complete pattern film 23 of the curing step of curing the shaped pattern film 23 can be formed on the surface of the device 21 by the most compact manufacturing process. Interfering pattern film 23, in turn, to impart a bright coating effect on the surface of the shell member 21; compared to the current tantalum coating process, wet process 'or gel process', the invention is not limited to the shell Whether the surface of the piece is a continuous surface such as a curved surface or a non-horizon, or the size of the area is not limited to the material of the shell member 21 itself, and the micro-scale of the pattern film can be maintained at an accuracy range of not more than 20 〇 nm. Provide a simple, low cost 'and easy to process The speed technology gives the shell member 21 a color appearance, which in turn makes the product have a colorful appearance that attracts people to purchase, and achieves the purpose of the creation of the present invention. △ However, the above description is only for the purpose of the invention, and the scope of the invention is not limited thereto, that is, the simple equivalent change of the patent scope and the description of the invention in the present invention. And modifications are still within the scope of the invention patent.
